Probably because you haven't personally turned on Safari's tracking protectors likely. Most browsers set their default protections to allow 'safe' ... IE- sponsors who pay the browsers for the service of listing the sponsors as 'safe'. Basically it's when you yourself reset browsers to a more 'strict' setting.
mush doesn't like anything above almost open as he likely uses all the cross tracking techniques possible. I have cross tracking and all cross tracking cookies blocked. So 'x' doesn't even load. So, I'll live without his fucking site then.
I've seen enough orangefatass and awww kittens to last the rest of time.
